Application led June 22, 1916. Serial No. 105,178.

To all whom t may concern Be it known that I, HOWARD M. BARBER, ay citi-zen of the United States, and resident of Stonington., in the county of New London and State of Connecticut, have invented a new and useful Improvement in Cutting and Folding Machines, of which the following is a specification,

The object of my invention is to providecertain improvements in cutting and folding machinesv whereby a plurality `of superimposed narrow webs may beI positively and accurately fed in absolute register through the sheet cutting mechanism to the folding mechanism, thereby permitting the sheet cutting. and' folding mechanisms to be run at a much higher speed than would otherwise be possible were the Webs not so positively and accurately fed.

My invention more specifically comprises two pairs of positively driven coacting endless belts, the belts being located beyond the sides of the webs and beyond the ends of thecoacting members of both the cutting and folding mechanisms, said belts having coacting bars which project inwardly from the belts in position to grasp between them the sides of the superimposed narrow webs, each pair of said bars havingy an interlocked engagement.

A practical embodiment of my invention is represented in the acccompanying drawings, in which,

Figure 1 represents the cutting and folding machine in side elevation,

Fig. 2 is a front View of the machine, and

Fig. 3 is a vertical section taken in the plane of the line A-- of Fig. 2, looking in the direction of the arrows.

l have shown three sets of rolls 1, 2, 8, 4, 5, 6, arranged to superimpose six narrow webs. Y

rlhecutting mechanism includes a pair of coacting rotary cutters 7, 8, carried by the shafts 9, 10, mounted in the side frames of the machine. rlhe folding mechanism iiicludes the male folding cylinder 11 andthe female folding cylinder 12, carried by their respectivecshafts 13, 14, mounted in the side frames ofthe machine. The male folding cylinder l1 is shown Ias' provided with vtwo sets of grippers 1,516', and two sets of folding, blades 17, 181 The female' folding cyliiidei' l1.2y is'v shown Aas provided with two sets or. fielding; jawsl la 20 arranged to' corset with the folding blades 17 and 18 respectively. j

The sheet delivery mechanism is herein shown.. asA .comprising the endless tapeccarriers 21, 22, the guide 28, the rotary drop,- per 24,. and the endless delivery carrier 25.

The cutting, folding and delivery mechanisms may be of any well known or approved form.

rlihe means for positively,feedingthe superimposed narrow webs through the cut-.

less belts 27 andv 29 pass around `the drum 31, and the lower endsl of said belts pass around sprocket wheels 32, 33. Fach pair of coacting belts 26, 27, and 28, 29, is provided with pairs of coacting bars 34C, 35 and 36, 37 respectively, which bars project inwardly from the endlessbelts in position to grasp between them the sides of the superimposed narrow webs. 'llhese pairs of inwardly projecting bars are equally spaced apart along the endless belts and act as teeth for engaging recesses 38, 39, and 40, eil, in the peripheries of the drums 30, 31 respectively, and recesses e2, 48, and 44, 45, in the peripheries of the male folding cylinder 11, and sprocket wheels 32, 33, for insuring the positive driving of these belts. Each pair of coacting inwardly projecting bars is also provided, the one member of a pair with a pin 46, and the other member with a recess for receiving4 the pin, to cause each pair of belts to have an interlocking driving engagement.

rEhe sprocket wheels 32, 33, are so arranged with respect to the male folding cy1- inder 11, that the pairs of endless belts w1ll travel together from the drums 30, 3l, downwardly past tlie rotaryl cuttersl 7,. 8', to the folding cylinder' 11an'd from thence short dieting@ along the, periphery er the folding cylinder" before the belts arefpermitted to separate'. 'this causes ttegnppers raie, te.

` at Vthe proper relative speeds.

the male folding cylindel1 11 to have ample time to close gently upon the advance edge of the superimposed narrow webs while the webs are still being held in register on the periphery of the folding cylinder, thus permitting the mechanism to be run at a much higher speed than would otherwise be possible.

Gearing 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 5s, 59, ce, 6i, e2, es, e4., 65, ce, provide means for driving the several mechanisms Guides 67, 68, are also provided for guiding the superimposednarrow webs from the cutting mechanism to the folding mechanism.

In operation, the narrow webs which pass over the rolls 12, 3, 4, and 5, 6, are superimposed and pass between the drums 30, 31, and are engaged at this point along their sides by the pairs of coacting bars projecting inwardly from the endless belts. These bars lfirmlyl grasp the superimposed webs and the belts convey the webs through the cutting mechanism, as hereinbefore described, where the advance edge of the webs, while still held in register by the bars, are engaged by either the set of grippers 15, or the set of grippers 16.

At about the same time the grippers engage the webs, the cutting mechanism operates to sever the same and the sheets are then carried around the periphery of the cylinder 11, until the folding mechanism of the cylinders 11 and 12 coacts to fold off the sheets to the cylinder 12, from which cylinfder 12 the folded sheets are delivered by the tape carriers 21, 22, guide 23. and sheet dropper 24, on to the endless delivery carrier 25.

Thus it will be seen that the superimposed narrow webs may be positively fed through the cutting mechanism to the folding mechanisr'nv in accurate register and held in such Y register a sufficient time on the male cylinder to permit the easy yoperation of the grippers. Claims on the cutting mechanism form the Ysubject-matter of a divisional application filed by me August 16, 1916, Serial Number 115,241, the claims in this present application being directed to the cutting and folding mechanism. Y

. It is evident that slight changes may be resorted to in the form, construction and arrangement of the several parts without departing from the spirit and scope of my invention; and hence I do not wish to limit myself strictly to the structure herein shown and described, but
